Definitions

• the invention relates to an alpine anchor for anchoring threaded rods in the ground or rock according to the preamble of claim 1.
• It consists essentially of a base plate which is placed on the ground or the rock and from threaded through the base plate to threaded rods which are screwed in different directions and angles through associated threaded holes in the base plate, so also in different angles and directions to be anchored in the ground or in the rock.
• Such an alpine anchor has proven itself on a large scale.
• a certain type of drill for mounting.
• Such a known drill consists of a drive motor which rotatably drives a chuck formed as a clamping chuck.
• a drive motor which rotatably drives a chuck formed as a clamping chuck.
• the thread pitches arranged at its circumference pulled the threaded rod into the ground As a result of the rotating drive of the threaded rod, it was thus progressively driven into the ground or the rock because the thread pitches arranged at its circumference pulled the threaded rod into the ground.
• the invention is therefore the object of developing an alpine anchor of the type mentioned so that a much more reliable installation of threaded rods through the base plate of the alpine anchor is possible.
• the invention has the further object of proposing a suitable assembly machine for this purpose and also to provide a use of an assembly machine and a method for assembling such an alpine anchor.
• the invention is characterized by the technical teaching of the independent claims.
• threaded rods with a length of up to 12 m can be driven without the user exerting any force and avoiding an accident risk.
• the invention therefore claims in general form any kind of (releasable) plug-in coupling between a stationary, machine-fixed fitting of an assembly machine and the base plate of the alpine anchor.
• An essential feature of the invention is therefore that the alpine anchor has a base plate in which a number of threaded holes are arranged, in which the threaded rods are screwed and that on or in the base plate in the vicinity of the threaded holes form receptacles for the rotational engagement of the fixed part of the Assembly machine are arranged, in which the assembly machine during insertion of the threaded rods is rotatably anchored.
• This is a first embodiment of the claimed plug-in coupling.
• fittings are z. B. formed as a square tube and are fixed to the housing connected to the non-rotatably driven part of the assembly machine. According to the invention, it is now provided that the assembly machine with the arranged at the front end fitting is first coupled in positive coupling with the arranged on or in the base plate shape receptacle, so as to achieve that the assembly machine before turning on the rotary drive with its front side rotatably with the Top of the base plate is coupled.
• the length and inclination of the fitting on the assembly machine with respect to the positive engagement in the base plate-side mold holder is selected so that the mounting machine in the rotationally fixed coupling on the base plate, ie when inserting the machine-side fitting in the base plate-side mold holder, free and must not be secured by hand from falling out or tilting.
• the base plate is now due to their threaded holes at least partially surrounding form receptacles is suitable to be rotatably coupled with the associated assembly machine.
• the base plate side threaded hole is arranged in an integrally formed on the base plate extension.
• the arrangement of the extension is only advantageous because thereby the length of the screw-in thread in the base plate is formed long.
• the extension can also be omitted and the threaded hole is - arranged directly in the base plate - without the extension lengthening extension.
• This has the advantage that the assembly machine no longer needs to be held freehand by the user, but the assembly machine is rotatably coupled before the start of assembly with the top of the base of the Alpine anchor, and then at the top of the mounting head (toward the visible side of the User) a threaded rod inserted into an arranged in the mounting head insertion and pushed there as far forward by hand until it is inserted into a rotationally driven in the mounting head drive sleeve.
• This drive sleeve establishes the frictional connection with the flat side of the threaded rod and drives the threaded rod in rotation.
• the drive sleeve rotates and works along the thread of the threaded rod so that it is driven in the feed direction through the threaded hole in the base plate down so particularly safe and accident-proof in the ground or Rock to be driven.
• the invention thus relates to any releasable coupling between an assembly machine and the associated threaded hole in the region of the base plate of the alpine anchor.
• This coupling is also referred to as a plug-in coupling.
• the form-locking coupling is formed as in or at the top of the base plate, the respective base plate-side threaded bore at least partially surrounding mold holder.
• This shape receptacle may optionally have two or three (triangle) or more than three (eg four or pentagon) each adjoining each other at an angle walls or abutment surfaces, which are suitable for the positive engagement of the mating surfaces of the machine-side fitting.
• the positive engagement of the machine-side molding can be done within the walls or abutment surfaces of the mold holder or outside.
• a combination of internal system and external system is possible.
• the first-mentioned embodiment means that the machine-side fitting abuts against the base-plate-side walls or abutment surfaces of the mold holder from the inside.
• the last-mentioned embodiment means that the machine-side fitting engages over the base-plate-side walls or abutment surfaces of the mold holder from the outside, in order to achieve the desired non-rotatable positive connection.
• the base plate-side mold holder may be formed as an approximately quadrangular surrounding frame around the threaded bore formed in the base plate, which projects beyond the threaded bore in the manner of a collar and forms with its longitudinal axis an axial extension of the threaded bore in the mold recess.
• the molding arranged on the machine side is inserted, so as to provide a releasable coupling between the housing of the assembly machine and the base plate of the alpine anchor.
• the at least partially surrounding the threaded holes form receptacles are not arranged as a raised surrounding frame above the surface of the base plate, but instead are formed as depressions in the base plate. So it only depends on a positive connection between a housing-fixed part of the assembly machine and the associated top of the base plate.
• any other coupling parts can be used instead of a square recess and an associated four-edged shape receptacle in the base plate. So z. B. hexagonal, oval, triangular or other shape recordings are arranged on or in the base plate, which interact positively with the same profiled fittings on the assembly machine and provide the desired rotary joint.
• Such a shape receptacle can also be formed by plug-in pins which engage in associated plug-in receptacles in the opposite part.
• the locking pins are arranged on the assembly machine and engage in associated formed as holes plug-in receptacles in or on the base plate.
• the mounting machine no longer has the formation of a simple drill, but instead a driven via a reduction gear mounting head has, in the interior of a rotationally driven lathe chuck is arranged, which is positively connected to the threaded rod.
• the threaded rod in this case can be inserted via an insertion opening arranged on the mounting head into a drive sleeve driven in rotation in the mounting head, which is driven in rotation and drives the threaded rod in a rotational manner in the longitudinal direction.
• this coupling additionally secures the mounting machine on the base plate against lifting in the longitudinal direction of the threaded rod.
• the plug couplings described here can be equipped with an additional lock against lifting the assembly machine from the base plate side mold holder.
• Such a lift-off can be as spring-loaded Ball lock or be designed as a clamping coupling.
• the extension of the plug-in coupling is claimed with a latchable or clampable lift-out.
• a first method step therefore, the threaded rod to be mounted is inserted in an insertion opening on the rear side of the mounting head and guided into the region of the drive sleeve arranged in the mounting head.
• a second method step then passes the threaded rod in positive engagement with the drive sleeve and in a third step, the arranged on the front of the assembly mold fitting is brought into positive engagement with the mold holder on the base plate, in which case the mounting machine is placed on top of the base plate .
• the drive motor of the drive machine is set in motion, and the threaded rod is driven with the rotationally fixed to the base plate coupled assembly machine through the threaded sleeve in the base plate into the soil or rock.
